PIONEER AVH-P4000DVD BYPASS HELP

LOOKING FOR SUM HELP WITH A BYPASS .
it is my understanding that this system uses a single pulse ground signal to pop up user agreement and then play dvd. i do not belive i have a sticker to peal for a plug n play format . any help would be good

I just bought an AVH-P4000 and thanks to the tips on this site, I can now "listen" to a DVD while driving and my passengers can watch.
I used a 4-pole Auto Relay from Radio Shack (Part#275-226, no 87a, just 85, 86, 87 & 30) and I followed the instructions and picture from this sight.
